Abstract: A handheld electric spray gun comprises a gun body, a spray can, a base for connecting the gun body with the spray can, and a housing. A nozzle is provided at the front end of the gun body. The upper portion of the housing is formed with a chamber, and the lower portion thereof is formed with a handle. The chamber is communicated with the gun body and provided with a motor therein. The handheld electric spray gun of the invention adopts a novel motor structure where a stator and rotor assembly is provided on the air-intake side of the blades, that is, the stator and rotor assembly is provided at the air inlet, so that the stator and rotor assembly may be forcibly cooled with cold air, thus the heat dissipation effect is greatly improved.
